Description:
All activity relating to Children and Young People who receive assessments and treatment from Mental Health Services is within the scope of the CYP Mental Health Services Data Set, where the patient has, or are thought to have:
- a mental health condition and/or
- a need for support with their mental wellbeing and/or
- a learning disability and/or
- Autism or any other neurodevelopmental condition
- The scope of the Mental Health Services Data Set requires patient record level data submission from services as follows:
For each patient attending a service located in England:
If the care is wholly funded by the NHS: the data submission for that patient is mandatory
If the care is partially funded by the NHS: the data submission for that patient is mandatory
If the care is wholly funded by any means that is not NHS: the data submission for that patient is optional.
For each patient attending a service located outside England, but commissioned by an English Integrated Care Board or NHS England specialised commissioner, the data submission is optional.
We currently have the data from Central and North West London NHS Foundation Trust from financial year 2017 onwards.

Researchers will have access to a secure workspace via an airlocked Azure
Virtual Desktop with a specific username and password. Researchers will get
specific access to a relevant subset of the datasets that are present in the SDE
catalogue for their project and will be able to carry out their research within
the safe haven. There are restrictions applied which prevent the researchers
from taking data out of the safe haven. Once the research is completed the
London SDE admin team will need to be contacted for any requests to egress
summary analysis out of the safe haven which will not breach 5 safe standards.
